DESCRIPTION PRACTICAL DESIGN: This is a great and fun way to train your dog/pet to learn to touch the button when they want to get out or in instead of scratching or barking, teaching them to be a "gentle dog". Any Breed, Any Age, Any Size, All Dogs TRIGGER SIMPLE: The dog doorbell is easy to activate. Simply touch or slide across the touchpad with your nose or paw. Dogs of any size will do, and even cats can handle it. Thanks to its power-saving system, this bell will last forever with your dog for many years. IP55 Waterproof: Built-in waterproof rubber ring, waterproof and environmentally friendly material; heat and cold resistant, which means your dog (or other pets) can touch/push the bell at any time, even if it rains or snows. Easy to install: No wiring required for dog potty training, you can place it anywhere in the house. And flexibly add or reduce receivers and transmitters according to your needs. Very easy to match and operate. Customize and control distance: With 55 first-chord ringtones and 5 levels of adjustable volume, you can choose your favorite ringtone sound (0-110 decibels), with doorbell ringtones, unique silent and do not disturb modes. The transmitter and receiver can communicate within the home up to 1,000 feet away. If your puppy starts ringing the bell just to go outside and play, you need to teach him that he only rings the bell to go potty. When he rings the bell, clip on his leash and lead him to where you want him to relieve himself. Give him a few minutes and if he does his thing, praise him and give him a treat. If he doesn't, take him back inside. Over time, your dog will learn that ringing the bell means the door will open and they can go out to relieve themselves
